“…This incident resulted in the shutdown of the pipeline for 246 days. 33 Therefore, it is urgent to clarify the leakage characteristics and diffusion laws associated with carbon dioxide pipelines. This initiative will aid emergency personnel in promptly and accurately identifying key parameters, such as leak size and location, thereby streamlining emergency rescue operations and advance the safety technologies within CCUS.…”

The leakage of carbon dioxide pipelines may result in significant incidents, such as fracture expansion, harm to humans and animals, and the loss of transported substances. Therefore, it is essential for us to accurately explain the processes of leakage and diffusion in carbon dioxide pipelines. Initially, this paper introduces the hazards of carbon dioxide leakage and the physical processes involved in such incidents. Subsequently, it systematically reviews recent research involving experiments and numerical simulations of carbon dioxide pipeline leakage at the entire process, including the in-pipe depressurization process, the near-field jetting process, and the far-field diffusion process. Moreover, it specifically discusses the differences in leakage processes between buried and overhead pipelines, highlighting the distinctive appearance resulting from leaks in buried pipelines. The Span-Wagner (SW) equation of state was found to accurately predict the thermodynamic behaviors of carbon dioxide during the entire process of pure carbon dioxide leakage and diffusion. Conversely, the GERG-2008 equation of state is better suited for carbon dioxide with impurities. Additionally, Homogenous Relaxation Model (HRM) and Delay Homogeneous Equilibrium Model (DHEM) have provided more precise predictions of carbon dioxide leakage and diffusion processes compared to the Homogeneous Equilibrium Model (HEM). The Computational Fluid Dynamics (CFD) model, in comparison to simplified models like Process Hazard Analysis Software Tool (PHAST), can better account for complex terrains, specific environmental conditions, and the impact of nearby structures or other obstacles on the carbon dioxide diffusion process. Its prediction aligns more closely with the actual results. However, research on buried carbon dioxide pipelines is still in its infancy, with only preliminary insights available at this time. Finally, this paper summarizes the research deficiencies on the leakage characteristics and diffusion laws of carbon dioxide pipelines, while providing a perspective on future research possibilities.

“…In the case of densely populated areas, such as most regions in Europe, pipeline routing through or near densely populated areas may become inevitable (Cosham and Eiber, 2008;Koornneef et al, 2010;Vitali et al, 2022). This poses a risk in the event of an accidental release.…”

“…The understanding of heat and mass transfer during the sublimation of a dry-ice bank can be crucial for the safe operation of equipment such as heat pumps [3] and refrigeration [4,5]. Moreover, dry-ice can form during the transport of CO2 in pipelines, its formation can impact the normal operation and increase the risk of ruptures [6,7]. Mazzoldi et al [8] analysed the sublimation of dry-ice banks analytically and presented a model to evaluate the energy balance.…”

The utilization of carbon dioxide in new technologies opens a wide range of interesting applications which depend strictly upon heat transfer phenomena. The momentum on the deployment of Carbon Capture Utilization and Storage (CCUS) infrastructures will potentially enlarge the diffusion of technologies for the utilization and recycling of CO2. Such applications, however, require appropriate laboratory investigations for a complete characterization of the CO2 thermo-fluid-dynamic behaviour. The safety management of carbon dioxide is important; thus, accurate modelling is needed since solidification and sublimation of dry-ice can be very challenging to predict analytically. One of the dry-ice applications is the utilisation in refrigeration cycles and in novel CO2 heat pump technologies. For this reason, knowledge about the entity of sublimating CO2 from a solid surface is crucial. This work proposes an innovative experimental setup for the measurement of temperature and convective velocity fields in the sublimating phenomenon of CO2 under atmospheric conditions by means of Particle Image Velocimetry (PIV). The experimental results have been compared and validated with numeric CFD models.
